2017 Acura NSX Technical Introduction

When the original Acura NSX made its debut 25 years ago, it forever changed the supercar universe by combining scintillating sports car styling and athletic performance—common traits long associated with the exotic car segment—with a new dimension of quality, exceptional ergonomics, comfort, and dynamic poise. The NSX introduced and defined Acura’s approach to “Precision Crafted Performance” with its cutting-edge design and innovative technology that provided accessible supercar performance for real drivers in the real world.

By making use of advanced new technologies such as a lightweight yet rigid all-aluminum monocoque body/chassis and a mid-mounted transverse V6, the original NSX challenged the conventional wisdom for a supercar. Its high-revving V6 engine featured a number of innovative production car technologies including forged pistons, titanium connecting rods and VTEC valve train.

Moreover, the NSX sought a more intimate connection between the car, the driver and the road underneath them, pursued through essential design elements – light weight, open and airy cockpit, and excellent ergonomics – creating an altogether new and paradigm-challenging definition of supercar performance.

Next Generation Concept

The overarching concept for the design and development of this next-generation NSX was the idea of a “human-centered supercar,” one that places the driver at the center of its mission in each and every element of its design and dynamic performance.

Respecting the foundational concepts of the original NSX—accessible supercar performance, everyday drivability, and openness to new technology—this next-generation NSX pursues an altogether new and revolutionary concept of Acura supercar performance – melding timeless NSX values with advanced technologies to create a New Sports eXperience.

Advanced Fundamentals (Timeless NSX Values)

First and foremost, the engineering team felt a tremendous responsibility to continue the fundamental innovation pursued by the original NSX team. Four foundational philosophies are fundamental to the timeless NSX values and essential to realize the new NSX concept and goals:

  • Total Airflow Management – a wholistic approach to thermal management and aerodynamic performance that supports and enhances dynamic response and high-speed stability without the need for active aero devices
  • Human Support Cockpit – a cabin that supports the driver and amplifies the driving experience with no sacrifice to comfort or everyday usability
  • Multi-Material Body – light and ultra-rigid body, applying material, construction and joining methodology optimized to the mission of each body component
  • Advanced Sports Package – optimizing the design and packaging in all the above aspects—the human package, the body, and finally the key components of the power unit to lower and center the mass of the vehicle.

Advanced Technologies

With these fundamentals in place, NSX engineers could effectively develop technical solutions needed to deliver the New Sports driving experience they sought.

To fully realize this New Sports eXperience, Acura electrifies the advanced fundamentals by leveraging its longstanding Direct Yaw Control knowhow through its Sport Hybrid Super Handling All-Wheel-Drive (SH-AWD) system, the first of its kind in the supercar realm.

The NSX concept for “zero delay” is more than acceleration, actually involving every aspect of the driver interface … the capacity to directly respond to the driver’s demands in all three phases of driving: Go, Stop, Turn (acceleration, braking and cornering). The NSX’s advanced power unit supports this achievement. Zero delay acceleration and active AWD traction power the NSX out of corners. Energy recovery supports direct and linear braking. And power strategically applied to the wheels directly creates a yaw moment to help turn the car according to the driver’s will.

Marrying new approaches to vehicle design fundamentals, including advanced body construction, component packaging and aerodynamic optimization, with an advanced and electrified new expression of Acura’s direct yaw control concept results in a supercar that faithfully translates the inputs of the driver with incredible fidelity and zero delay while minimizing the driver’s workload—qualities that define the New Sports eXperience.

Design, Development and Manufacturing

Development of the next-generation NSX involved a global team of engineers and designers, with development of the Sport Hybrid power unit centered in Tochigi, Japan. Development of the body, chassis, electrical, interior and other vehicle technologies including total system integration, was concentrated in Raymond, Ohio. Initial styling design for the NSX was conducted at the company’s Wako design studio in Japan, and was evolved for production by the Acura Design Studio in Los Angeles.

Throughout its roughly four-year development, the fundamental “human-centered supercar” concept for the next-generation NSX remained clear and consistent. However, the technologies and means by which the R&D team would realize their concept underwent a process of continual improvement and evolution, most notably in the area of engine design. Whereas the original direction called for a transverse-mounted, normally aspirated V6, the NSX development concept evolved to a new and more challenging approach: an all-new bespoke twin-turbocharged, longitudinally mounted V6. This radical re-imagination of the engine design had profound implications for every element of the NSX design—the package, cooling, aerodynamics, chassis and more.

The NSX has been tested and tuned on streets and race circuits around the world. Primary development was conducted at the Transportation Research Center adjacent to Honda R&D Americas Ohio Center as well as the Honda Takasu proving ground in northern Japan before moving to tracks such as Virginia International Raceway and the famed Nürburgring, followed by global “genteki” events (“at-the-spot” verification) which took NSX on public roads throughout the U.S. and Europe and beyond.

Construction of the NSX will take place at the new Performance Manufacturing Center (PMC) in Marysville, Ohio. The PMC was designed to innovate both the means and the methods of producing low-volume specialty cars and to realize challenging new ideas for next-generation craftsmanship and quality established by the NSX manufacturing team.

The PMC employs approximately 100 associates, including 70 highly skilled manufacturing technicians engaged in body construction, painting, assembly and quality confirmation of the NSX. Among its many innovative processes is the use of robotic MIG welding for the construction of the NSX’s aluminum space frame.

The NSX’s bespoke twin-turbocharged V6 engine is assembled by master engine builders at the company’s engine plant in Anna, Ohio. The engine is broken in on a dyno so that it’s track-ready when it leaves the factory. Then it’s mated to a direct drive motor (part of the hybrid system) and precision balanced as an assembly. Its bespoke 9-speed dual clutch transmission is then attached to the engine and this portion of the total power unit is sent to the PMC. The Twin Motor Unit (TMU) and other hybrid system components are built in Japan and shipped to Ohio for final assembly, completing the overall power unit.

2017 ACURA NSX: Dynamic Performance

Dynamic Concept

The NSX was created to revolutionize supercar performance, delivering a more vivid, immediate and intuitive dynamic experience with zero-delay acceleration, braking and handling – such that the vehicle responds according to the “will” of every driver’s inputs, but truly comes “alive” in the hands of skillful drivers. Fundamental dynamic concepts are as follows:
